. Application ledseptember 1, 1922. Serial No. 585,748.'

l certain wellT known tractors embody powerul'air fans that subject the operators thereof to objectionable blasts of hot air and dust.

The object, therefore, .of myl saidinvention is the provision in a'tractor of a "shield,

susceptible of yready application, and pos-` sessed of the capacity of function of deflecting the blast of hot air and dust from the tractor fan down around the motor, thereby d relieving the eyes and bodyv of the operator from heat and dust. A u

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure l is a side elevation showing a por- .tion of a welll known make of tractor equipped with my novel shield..

Figure 2 is a detail plan v1ew wlth the fuel tank lof the tractor -removed to better show the arrangement of my novel shield.

' Figure 3 is a longitudinal vertical sect1on showlng the' inter-position of my shleld bed tween the motor and the fuel tank.

Figure 4 is a transverse section takenin the plane indicated by thehne 4-4 of Figure` 2 and showing the preferred configuration of the forward pprtion of the shield.

Figure 5 is a longitudinal section on the line 5--5' of Figure 2, showing the preferred form of shiel Figure 6 isa plan view of the blank from which is formed theshield constltutmg the best practical embodiment of my invention of which I am cognizant.

Similar numerals of reference de slgnate corresponding parts in all of the vlews of the drawings.

'The wellknown make of tractor alluded to kcomprises among other elements a motor 1 of internal combustion type, a fuel tank 2 above the motor and in spaced relation' thereto, and a fan casing 3 in front of the motpr. The operators station is behind the motor and fuel tank in convenient proximlty to the steering wheel designated by 4.

In accordance with my invention I provide a shield 5 preferably in the'form of a metallic plate of twenty four gauge, the said platebeing of general rectangular form and being interposed between the motor 1 and 60 the fuel tank 2, Figures 1 and 2, So as to effectively guard and protect -the operator against'the blast'yof hot air and dust that the fan in thecasing 3 tends to throw'rear-` wardly. The shield 5 inthe performance of; 65 the said function acts after the manner ofa baffle to deflect thehot air and 'dust downwardly about the motor 1,` and in order to enable' the shield tobetter serve the purpose- I provide the rear end and the side edges 'of117- 0 the shield with "pendentflanges numbered' 6 and y7, respectively. I also` curve the forj ward portion of the shield transversely asbest shown in Figure 4 at 9 and Sky-and ythe portion of the-forward'end ofthe shield 75 i between the forward extensionsv designated by 91, I curve upwardly as designatedpby 9a in Figures 3 and 5. Thus the shield intercepts. and deflects' theblast from' the y fan downwardly and in that wayaverts subjecting the operator to discomfort and injury so'that he is better able to steer the tractor and operate the samev to the best advantage., This will'be better understood when it is stated that in'vi'rtue of the'forwa'rd upward 85 f curvature 9, all of the blast' from the fa'n is caught and prevented from passing over the shield, andis caused to fbllow the curve and move under the shield. The curve or flange 6 at the rear end ofthe shield catches the v'90 blast and deflects the same downward. The intermediate curvature 9, Figures 3, 4 and l5 accommodates the fuel tank 2; and it will be readily appreciated that the said: depression or curvature 9 guides the air and dust to the 95 curved portions 9i and the flanges 7. These portionsQX-and, flanges 7 extend laterally outward to a sufficient extent to catch all of the fan blast andv concentrate the same inwardlyv with. the result that escal eV of por- 'Ootions ofthe blast past the edges o the shield is precluded. In other words the shield transversely curved as illustrated acts as a` hood above the blast, and has the effect of Y maintaining a strong draft of air down-105 wardly upon and around'l themotor block- .whichconduces to cooling of the motor'. The

forward extensions 9z ofthe shieldserve to` concentrate and gather in all of the air directed rearwardly by the fan, and forsuch vreason I preferto employ thesaid extensions 91.

when the said nuts are turned tight the forward end of the shield will be strongly and securely fastened in position snugly against the said projection. I provide the.

notch 10 inthe rear end of the shield to receive the air-washer pipe 13 of the tractor, Figure 2, and the aperture 9C serves to receive and to enable the rear portion of the shield to rest on the usual comparatively large part of the conduit 14 between the fuel tank 2 and the motor l; the said conduit being made up of detachably connected members which are lconnected together subsequently to the positioning of the shield. Manifestly when arranged as Stated the rear portion `of the shield is adequately support- .ed and held against casual lateral movement.

lIn addition to the prime advantagev ascribed to my novel shield, the same serves secondarily to shed rain and thereby prevent the same from detracting from the efficiency of the wiring and coils of the motor.

It will be apparent from 4the foregoing that the shield vmay be stamped from sheet metal, Figure 6 and may then be appropriately flanged or shaped as shown in Figures 4 and 5.

My novel shield is adapted to be used to advantage in all tractors, and it is within the purview of my invention to appropriately build the shield formed of any material compatible with its purpose in a tractor at the time of manufacture thereof or to install the shield in a tractor after the manufacture of the latter. In either case the shield will guard the operator, more particularly his feet and legs against heat,l

and will .effectively protecthis face and eyes agalnst dust, sand grit and the like and will g obviate the necessity of the operator inhal- I assistance of skilled labor.

ing dust.

While my improved shield is calculated to materially increase the sale of tractors by meeting the mentioned objection frequently offered against the make of tractors illustrated, it will be appreciated that the shield is inexpensive and is adapted to lbe quicklyand easily installed' in tractors at present 1n use without thenecessity of invoking the ment of the parts embraced in the presentl and preferred .embodiment of my invention inorder to impart a full, clear and exact understanding Vof the said embodiment. I do not desire, however, to be understood as confining:I myself to the specific construction and relative arrangement of parts inasmuch as in the future practice of the invention various changes and modifications may be made such as fall within the scope of my invention as definedin my appended claims.
